INSPECTION PROCEDURE
HINT:
SAfter completing repairs, confirm that P1271 and/or P1272 is not present again.
SIf P0200 and P1271 are present simultaneously, there is open in the INJF wire harness between the
EDU and ECM, or there is open in the wire harness for both injector and pressure discharge valve.
SRead freeze frame data using the hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or
rich, and other data from the time the malfunction occurred.

DTC P 1238 INJECTOR MALFUNCTION
HINT:
S For more information on the injector and the common rail system, see page 05 −255.
S If P1238 is present, refer to the diagnostic trouble codes (DTCs) table for the fuel system on page
05 −255.
CIRCUIT DESCRIPTION
The ECM detects combustion deterioration for a specific cylin-
der.
HINT:
SThe cylinder, which has compensation value for INJ VOL
that varies from other cylinders, may be malfunctioning.
SIf DTC P0093 (Fuel leaks in high −pressure area) is pres-
ent simultaneously, leakage malfunction of the cylinder
probably be occurred.
SIf DTC P0200 (Open or short in EDU or injector circuit) is
present simultaneously, there probably be faulty circuit lo-
cated between the ECM and the injector including the
EDU.
SIf only DTC P1238 (Injector malfunction) is present, prob-
ably injector mechanical malfunction or insufficient com-
pression (valve clearance etc) has occurred, not an open
or short malfunction of the ECM, EDU and injector circuit.
SSolenoid valve of the injector is the same type that of the
pressure discharge valve.

AVENSIS Supplement (RM1045E)
MONITOR DESCRIPTION
P 1238 (Injection malfunction, exclude open or short in injector circuit):
This DTC will be set if the engine speed fluctuation between each cylinder is large. The ECM monitors
changes in the crankshaft rotation speed using the crankshaft position sensor for detecting poor combus-
tion. Also, it identifies a faulty cylinder using the camshaft position sensor. The fluctuation counter incre-
ments when irregular crankshaft rotation speed variation exceeds the threshold at idling. Therefore, either
one of the cylinders has very poor combustion (Rough idle), the ECM sets this DTC.

INSPECTION PROCEDURE
HINT:
SIf DTCs other than P1238 are present simultaneously, first perform troubleshooting for them.
SRead freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P 1238)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
